FIELD OF THE INVENTION

The present invention relates to a method of making a book or bookletcover including a metal sheet supporting a sheet-like informationcarrier.

The invention further relates to a book or booklet cover including ametal sheet supporting a sheet-like information carrier, which sheet hasa first face and an opposite second face, with the first face of thesheet on a first side of a metal sheet, the metal sheet having a portionthat extends beyond at least one edge of the sheet.

BACKGROUND OF THE INVENTION

Among the many variations within the field of sheet-like informationcarriers there are a couple that should be mentioned in this context.

The traditional book comprising a cover and a number of content pages isvery well-known.

Plastic boxes where a printed inlay is loosely placed inside the box,often together with other items, is likewise a well-known solution.

GB 2249859 discloses a media packaging where on the outside a number ofleaves are placed for containing and displaying various information orartwork.

Commonly known problems related to these information holding articlesare the need to individualize the cover for the book in order to achievethe right dimensions and the ability to maintain the sides of the coveressentially parallel when the book is closed or have the inlay looselyplaced in the cover.

DK 179915 B1 discloses an information holding article that may bemanufactured in a standard size and being adapted for variations in thecontent and hence reduce the effort of individualising the informationholding article. The information holding article comprising an innerpart and an outer part, where the inner part comprises a number of pagesadapted for holding printed information and optionally comprises one ormore parts for holding an information carrying medium or an object,where the outer part comprises a plastic cover with a first and a secondside element and where a back element is provided between the first andthe second side element an being adapted for mutual pivotal movementbetween the back element and the first and/or the second side element,where the inner part is connected to the plastic cover at one of thefirst side element, the second side element or the back element, wherethe two side elements are spaced apart when the inner part is connectedto the plastic cover, where the pages of the inner part has a thicknessless than the width of the back element, and where the inner part isadapted to fit a the width of the back element by including, togetherwith the pages, a thickness correcting element to the inner part. Herethe metal cover is fastened to the book by gluing.

OBJECTIVE OF THE INVENTION

The object of the present invention is to therefore provide for asheet-like information carrier that may be manufactured in a standardsize and being adapted for variations in the content and hence reducethe effort of individualising the information holding article withoutneed for using glue for attaching a cover in shape of a metal sheet to asheet-like information carrier.

This is achieved by a method of making a book or booklet cover includinga metal sheet supporting a sheet-like information carrier comprising thesteps of: placing a first face of the sheet-like information carrier ona first side of a metal sheet, which metal sheet extends et least beyondone edge of the sheet; bending in a rounding way a portion of the metalsheet along an edge thereof, for said portion to bear against and toelastically press on said sheet, thereby forming the book or bookletcover, wherein the edge is bend in an angle of 270 degrees or more inrelation to a metal sheet with an unbended edge.

By bending an edge of the metal sheet without bending it into a sharpbend in such a way the an outmost part or portion of the sheet along anedge is pressed against a surface of the first face of the sheet-likeinformation carrier, holding the second face of the sheet-likeinformation carrier against the first side of the metal sheet.

The bended portion of the metal sheet can be bend in a radius, whichbending radius is greater than a thickness of the metal sheet in such away that the bended portion bended along the edge elastically pressesagainst the surface of the first face of the sheet-like informationcarrier, holding the second face of the sheet-like information carrieragainst the first side of the metal sheet.

Hereby is achieved that the metal sheet can be fastened to thesheet-like information carrier without use of glue or other kind ofadhesive.

A method of making a book or booklet cover including a metal sheet 2supporting a sheet-like information carrier 1 can be carried out asfollows.

A first face 3 of the sheet-like information carrier 1 is placed on afirst side 5 of the metal sheet 2, in such a way that the metal sheet 2extends at least beyond one edge 10 of the sheet 1. Then a portion 11 ofthe metal sheet 2 is bend in a rounding way along an edge of the metalsheet 2, for said portion 11 to bear against and to elastically press onsaid sheet-like information carrier 1. In some embodiments this issufficient to hold the sheet-like information carrier 1 firmly in themetal sheet 2 by the pressure of the bended portion 11. In otherembodiments abutting edges of the metal sheet 2 can be bend to morefirmly hold the sheet-like information carrier 1 within the metal sheet2.

When bending in a rounding way a portion 11 of the metal sheet 2 alongan edge thereof, for said portion 11 to bear against and to elasticallypress on said sheet 1 the book or booklet cover is formed, where theedge 7 is bend in an angle of 270 degrees or more in relation to a metalsheet 2 with an unbended edge.

In an embodiment of the method the edge 7 is bend in an angle a being ina range between 180 and 270 degrees in relation to a metal sheet 2 withan unbended edge 7, with the effect that a first edge part 8 of the edge7 of the metal sheet 2 can carve into the material of the sheet-likeinformation carrier 1, providing a holding force.

In another embodiment, the edge 7 is bend in an angle a being 270 degreein relation to a metal sheet 2 with an unbended edge 7, with the effectthat it is possible to provide a contact area corresponding to amaterial thickness of the metal sheet 2 pressing against a second face 4of the sheet-like information carrier 1, thereby squeezing thesheet-like information carrier 1 between the edge 7 of the roundedportion 11 of the metal sheet 2 and the first side 5 of the metal sheet2, providing a holding force.

In another embodiment, the edge 7 is bend in an angle a being in a rangebetween 270 and 360 degrees in relation to a metal sheet 2 with anunbended edge 7, with the effect that it is possible for a second edgepart 9 of the edge 7 of the metal sheet 2 to carve into the material ofthe sheet-like information carrier 1, providing a holding force.

In another embodiment, the edge 7 is bend in an angle a being 360degrees in relation to a metal sheet 2 with an unbended edge 7, with theeffect that it is possible to provide a resilient contact area of thesecond edge part 9 of the portion 11 of the metal sheet 2 pressingagainst the second face 4 of the sheet-like information carrier 1,providing a holding force.

In another embodiment, the edge 7 is bend in an angle a being more than360 degrees in relation to a metal sheet 2 with an unbended edge 7, withthe effect that it is possible to provide a resilient contact of theportion 11 of the metal sheet 2 pressing against the first face 4 of thesheet-like information carrier 1, providing a holding force.

An example of a machine with a tool for bending a portion of a metalsheet in a rounded way around an edge portion of a sheet-likeinformation carrier is shown in FIGS. 1 to 4 , showing different stagesduring the process.

This is just for mentioning one example, different tools may perform thesame bend.

In FIG. 1 the tool comprises a lower part 20 and an upper part 21, thelower part 20 comprising a support surface 22 on which the articles 1, 2for forming the book or booklet cover is placed and a first tool part 23having a grove 24 for performing the rounded bending of the portion 11of the metal sheet 2. The upper part 21 comprises a second tool part 25comprising an inwardly rounded edge 26 for completing the rounding ofthe portion 11 of the metal sheet 2, when the tool parts 23, 25 are puttogether.

When moving the upper part 21 towards the lower part 20, the first toolpart 23 is moved towards the edge 7 of the metal sheet 2 and the portion11 is forced along the rounding in the grove 24 thereby being bend in arounded way. The traveling distance of the first tool part 23 determineshow much of the portion 11 to be bend and the dimension of the grovedetermines the dimension of the bended edge portion.

In FIG. 2 , the first tool part 23 is moved towards the second tool part25 and the portion 11 of the metal sheet 2 is beginning the bending.

In FIG. 3 , the bending is completed and in FIG. 4 , the tool parts 23,25 are moved apart from each other and the end product can be seen.

FIG. 5 shows a sheet-like information carrier 1 placed on a metal sheet2 before being joined in an edge portion. The sheet 1 comprises a firstface 3 and an opposite second face 4, where the first face is placedagainst a first side 5 of the metal sheet 2. The metal sheet 2 has anopposite second side 6, which second side rest on the support surface 22of the tool during bending. A portion 11 of the metal sheet 2 comprisesan edge 7 having a first edge part 8 and a second edge part 9. The sheet1 shows an edge 10.

The product obtained by completion of the process is a book or bookletcover including a metal sheet 2 supporting a sheet-like informationcarrier 1, which sheet 1 has a first face 3 and an opposite second face4, with the first face 3 of the sheet 1 on a first side 5 of a metalsheet 2, the metal sheet 2 having a portion 11 that extends beyond atleast one edge 10 of the sheet 1, where the portion 11 of the metalsheet 2 has a rounded bend along an edge thereof, the portion 11elastically pressing against said sheet 1.

In an embodiment as shown in FIG. 7 , the metal sheet 2 has an edge 7which is bend in an angle a in a range between 180 and 270 degrees inrelation to a metal sheet 2 with an unbended edge 7. Hereby the firstedge 8 carves into the sheet 1 forming a better grip than if the edge 7of the metal sheet 2 was just folded around the edge of the sheet 1.

In an embodiment as shown in FIG. 6 , the metal sheet 2 has an edge 7which is bend in an angle a being 270 degree in relation to a metalsheet 2 with an unbended edge 7. The angle a mentioned in the differentembodiments are indicated in FIG. 6 , which angle a refers to an angularposition of the edge 7 compared to an edge 7 of a sheet with an unbendededge.

In embodiments as shown in FIGS. 8, 9 and 10 , the metal sheet 2 has anedge 7 which is bend in an angle a being more than 360 degrees (FIG. 10), preferable 360 degrees (FIG. 9 ), more preferable in a range between270 and 360 degrees (FIG. 8 ) in relation to a metal sheet 2 with anunbended edge 7.

As shown in FIG. 8 , the second edge 9 carves into the sheet 1 forming abetter grip than if the edge 7 of the metal sheet 2 was just foldedaround the edge of the sheet 1.

Hereby it is possible to retain the sheet-like information carrier 1 inrelation to a metal sheet 2, where a portion 11 that extends beyond atleast one edge 10 of the sheet 1, where the portion 11 of the metalsheet 2 has a rounded bend along an edge thereof, the portion 11elastically pressing against said sheet 1 and thereby attaching the twoparts together without need to use any adhesive material.

The first side or page of the sheet-like information carrier can be ofsame thickness as the rest of the pages in the book or booklet, or thefirst side or page can be thicker than the rest of the pages in the bookor booklet. The same apply to the last side or page.

Bending in a rounding way should be understood as when the edge of themetal sheet is bend, the side which is bend around the bending edge isrounded and do not form a plane inner surface. Hereby is achieved thatthe edge which is now bend more than 180 degrees in relation to itsinitial position will be able to press against a sheet or the like onwhich the metal sheet 2 is placed to cover, without the inner portion ofthe bended edge pressing against the inner sheet. The part formingcontact with the inner sheet is the edge of the metal sheet 2 or thecorner lines of the edge.

In FIGS. 6 to 10 it is shown that a hollow channel is formed in the edgeportion of the cover.
